Description

Method and device for identity verification using human biological characteristics

The invention relates to the field of identity verification, in particular to a method for identity verification using human biological characteristics; the invention also provides a device for identity verification using human identity characteristics.

With the advancement of society and the development of technology, people are increasingly demanding the security and convenience of access control. Automatic, fast, accurate, and secure authentication is a prerequisite for many network operations; traditional identity Authentication methods, such as passwords, passwords, and identity documents, have been difficult to meet the needs of the new situation.

In recent years, new technologies that use human biological characteristics (such as fingerprints, palm prints, faces, facial features, voice prints, etc.) to achieve identity verification have gradually received attention. The basic steps are as follows: the user first registers the human biometrics, that is, enters the human biometrics and collects the feature code, and then stores the feature code; thereafter, each time the user needs to perform identity verification, the user's human body must be entered again The biometric feature is collected and the feature code is compared; the feature code is compared with the feature code stored at the time of registration, and the identity verification process is completed by judging whether the two match.

Due to the two natural advantages of uniqueness (different for everyone) and immutability (which will not change throughout life), this new technology has been widely used in many fields such as finance, telecommunications, transportation, education, and medical care. Promotion and application.

With the maturity of human biometrics, this new technology has also been applied in areas such as online banking, online payment systems, and remote access to corporate servers that require remote access control. In these applications, users may use different terminal devices when registering human biometrics and issuing authentication requests. For example, users use the terminal device provided by the application server to enter registered human biometrics, and perform remote storage when needed. When taking the time, the user uses the sensor of the mobile terminal device to input the biological characteristics of the human body, and initiates a remote login authentication request. In this way, a new problem has arisen. After launching their own biometrics collection terminal equipment, each equipment manufacturer has also developed a feature code collection algorithm and a feature code comparison algorithm corresponding to its equipment, because they are different. Device manufacturer's feature code collection algorithms and feature code comparison algorithms are different, resulting in equipment of different manufacturers cannot be interconnected and interoperable. Users need to use the terminal equipment of each manufacturer to register human biometrics, otherwise the correct identity may not be obtained. verification.

Taking the most widely used fingerprint recognition technology as an example, after a user first registers a fingerprint using the fingerprint collection terminal device of manufacturer A, the registered fingerprint characteristic code obtained by analyzing the fingerprint image is stored in the fingerprint database; next time the user performs identity During the verification, the fingerprint collection terminal device of manufacturer B was used to obtain the verification fingerprint feature code, and the fingerprint authentication center would obtain the fingerprint fingerprint database from the fingerprint database. The user's registered fingerprint feature code is compared with the verification fingerprint feature code; because the fingerprint collection terminal device's feature code collection algorithm used twice is different, the generated fingerprint feature code is also different, no matter which ratio is used None of the algorithms could get correct results, which caused the user's authentication to fail. In order to avoid this situation, when registering a fingerprint, the user must perform the fingerprint identification on the two types of fingerprint collection terminal equipment separately, and store the fingerprint signature obtained in each fingerprint into the fingerprint database, so as to ensure the successful identity verification in the future. Because terminal equipment of different manufacturers cannot be interconnected, the operation steps involved in the above process are cumbersome, and it cannot meet the needs of users to quickly and easily implement identity verification. At the same time, it also affects the application of this new technology in the field of remote access control.

Numerous specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar promotion without departing from the content of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

As shown in FIG. 1, FIG. 1 is a flowchart of a first embodiment of a method for authenticating an identity using a biological feature of a human body provided in the present invention. In this embodiment, a terminal device requesting a verifier provides a human body requesting a verifier. Biometric files. The following description is made with reference to FIG. 1.

Step S100: Receive a human biometric profile corresponding to a specific identity as a reference profile.

This step is the registration process of the user's human biological characteristics. For implementation In the identity verification method provided by the present invention, a user must register human biometrics for the first time, that is, a user inputs human biometrics on a terminal device, and the terminal device generates a corresponding human biometric file based on the human biometrics input by the user. If the user provides human biological features such as fingerprints, faces, facial features, palm prints, then the terminal device generates corresponding image files; if the user provided human biological features are voiceprints, then the terminal device generates corresponding sound effects files . The device or system used for identity verification receives the image file or sound effect file and stores the file, thereby completing the registration process of the user's human biometrics, and the registered human biometric file serves as the user's subsequent identity verification. Base file.

The user inputs human biometrics from the terminal device. After the terminal device performs necessary preprocessing, the human biometric file is generated, and the user's registration request is uploaded to the device or system for identity verification. The registration request includes the use of In addition to the human biometric profile of the user, it also contains the registered user identification and the type and / or model of the terminal device used for registration.

The reason for providing a registered user identity is because the present invention provides an identity verification method, whose purpose is to determine whether the biometric profile of the human body to be verified for a specific user identity is the same as the reference profile corresponding to the specific user identity. In this process, the user identity is an intermediate link that associates the biometric profile and the reference file of the same user with the human being to be verified. Therefore, the unique user identity information should be provided when the user is registered, and the identity initiated later Provide the same user identification information when verifying the request.

The registration request includes the type and / or type of terminal device providing the reference file The model is to enable the collection algorithm and / or the comparison algorithm corresponding to the terminal device to be retrieved according to the type and / or model of the terminal device in the subsequent identity verification process.

After receiving the above registration request sent by the terminal device, the device or system used for identity verification extracts the registration information and stores the registration information to complete the user registration process.

The terminal device can prompt the user to input the user ID by scanning the ID card, or the user ID can be input by pressing keys, or by other methods such as binding with the mobile device number. How the terminal device obtains the user ID is not the present invention. It is critical that the present invention is not limited.

The terminal device may read the pre-written data on a specific area of the storage medium to obtain the type and / or model of the terminal device, or may adopt other methods, which are not limited in the present invention.

The interaction between the terminal device and the device or system used for identity verification may be through a USB interface, a network interface, or a wireless transmission interface. The specific interface method is not limited by the present invention.

In this embodiment, Mr. Zhang uses the fingerprint sensor of the Xiaomi 2S mobile phone to input his fingerprint to generate a fingerprint image file with a suffix of jpg. The user ID of Mr. Zhang obtained by the Xiaomi 2S mobile phone is 0001, and the Xiaomi 2S mobile phone will send Mr. Zhang The registration request is uploaded to the fingerprint authentication center for identity verification through the wireless transmission interface.

After the fingerprint authentication center receives the request uploaded by Xiaomi 2S mobile phone, it must first discriminate whether it is a registration request or a verification request. Generally, two methods can be used. Method one: The request information includes the identification of the request type and the fingerprint identification. The identification center reads the identification and makes a judgment. In another way, the request information does not include the identification of the request type. In this case, the fingerprint authentication center searches the fingerprint database storing the registration information according to the user identification provided in the request. If no registration information corresponding to the user ID is found in the fingerprint database, the user ID has not been registered. After determining that the terminal device uploads the registration request, the fingerprint authentication center extracts the information provided in the registration request and stores it in the fingerprint database in the following format to complete the fingerprint registration process of the user Mr. Zhang.

Fingerprint database example

It should be noted that in this embodiment, the fingerprint image file is stored in a specific file directory fpimg, and the fingerprint image file in the fingerprint database contains the storage path and specific file name of the fingerprint image file. When the fingerprint image file registered by Mr. Zhang is extracted, the corresponding fingerprint image file can be read by accessing the path.

In other embodiments, if the user provides a voiceprint during registration, the device or system used for identity verification may receive the user ’s registration request in a similar manner to the above, and the received sound effect file It is stored in a specific file directory, and the storage path and specific file name of the sound effect file are written in the corresponding row of the database. When the sound effect file registered by the user needs to be extracted, the path can be read by accessing the path Corresponding sound effects files.

In other embodiments, the user registration information may also be stored in a common data file or a data table, as long as the user registration information can be extracted therefrom as required. Databases, data files, and data tables can be stored in the local storage area of the device or system used for identity verification, or on other network storage devices. The specific storage form and location are not the core of the invention. The invention does not limit this.

Step S101: Receive a human biometric profile of a requesting verifier.

The requesting verifier uses a terminal device capable of providing a biometric profile of the human body, enters the human biometrics of the requesting verifier, requests the terminal device of the verifier to generate a human biometric file requesting the verifier, and the device or system for identity verification receives the Request a biometric profile from the verifier.

The identity verification request initiated by the requesting verifier's terminal device includes, in addition to the biometric profile of the requesting verifier, the user identification of the requesting verifier and the type and / or model of the terminal device of the requesting verifier. A user identification, for extracting a registered human biometric file (ie, a reference file) corresponding to the user identification from the stored human biometric data, and requesting the type and / or model of the terminal device of the verifier, Used to obtain the acquisition algorithm and comparison algorithm corresponding to the device.

In this embodiment, when Mr. Zhang uses the application on the Iphone4S mobile phone, remote authentication is required. Mr. Zhang entered his fingerprint image through the fingerprint sensor of the Iphone4S mobile phone, and the Iphone4S mobile phone directly Mr. Zhang ’s fingerprint image file varify_0001.jpg, user identification (0001), and device type and / or model are then uploaded to the fingerprint authentication center, and the fingerprint authentication center receives the information to be verified.

Step S102: Obtain the type and / or model of the requesting verifier terminal device used to provide the human biometric profile of the requesting verifier, or obtain the type and / or model of the specific terminal device used to provide the reference file.

In the authentication request uploaded by the terminal device, the user identifier of the requesting verifier and the type and / or model of the terminal device of the requesting verifier are provided. The type and / or model of the terminal device of the requesting verifier can be obtained by directly reading the information. Or, according to the user identification of the requesting verifier, access the stored human biometric data, and find the type and / or model of the terminal device used for registration corresponding to the user identification of the requesting verifier (that is, for providing a reference file) Type and / or model of the specific terminal device).

Because the device or system used for identity verification receives the human biometric profile of the requesting verifier, rather than the signature to be verified of the human biometric of the requesting verifier, a specific collection algorithm is used to receive from the received The requesting verifier collects the signature to be verified from the human biometric file. Regardless of whether the human biometric file provided by the user is an image file or a sound effect file, it involves the selection of the acquisition algorithm. Here, the human biometric image is taken as an example to explain the idea of selecting the acquisition algorithm. In terms of identity verification, the basic idea of choosing a collection algorithm is the same.

Because the biometric image of the human body input by the user on the terminal device is usually It is a gray image with more noise. Terminal equipment usually also needs to perform certain pre-processing operations to improve the quality of the input human biometric image, remove noise, and get a clear dotted line image. However, there are differences in the methods of acquiring images from terminal equipment of different manufacturers, and the image preprocessing algorithms used are not exactly the same. The clarity, contrast, and noise of the biometric images of the human body that are finally obtained are all different. And terminal equipment manufacturers can use the targeted acquisition algorithms and comparison algorithms to capture the characteristics of the images of their own devices, collect specific locations and a specific number of feature points, and perform targeted comparisons to achieve The best identification effect, so it is most reasonable to use the acquisition algorithm that comes with the terminal equipment that provides the image. Considering the objective needs of the interconnection and interoperability of terminal equipment of different manufacturers in the present invention, it is necessary to adopt a unified acquisition algorithm to collect feature codes from human biometric images from different devices. In theory, as long as a unified acquisition algorithm is used, However, in order to obtain a satisfactory implementation effect, a collection algorithm of a terminal device that provides a reference image or a collection algorithm of a terminal device that requests a verifier is a better solution.

Based on the above considerations, in this embodiment, one device can be selected arbitrarily from the Xiaomi 2S mobile phone that provides Mr. Zhang's registered fingerprint image file (that is, the reference file) and the Iphone 4S mobile phone that provides Mr. Zhang's fingerprint image file to be verified, and The acquisition algorithm corresponding to the type and / or model of the device is selected. In this embodiment, a Xiaomi 2S mobile phone is selected.

In step S103, a collection algorithm used by the terminal device is retrieved according to the type and / or model of the terminal device.

According to the type and / or model of the terminal device selected in step S102, Find pre-configured human biometric algorithm configuration information, and retrieve the collection algorithm corresponding to the type and / or model of the selected terminal device. In the pre-configured biometric identification algorithm configuration information, for each terminal device, a type and / or model of the terminal device, a collection algorithm and a comparison algorithm corresponding to the terminal device are set. The configuration information of the human biometric identification algorithm is pre-configured, and may be in the form of a table, or stored in a database, and may be stored locally in a device or system used for identity verification, or may be stored in other On the equipment, the present invention does not limit the specific storage form and location.

In this embodiment, for the Xiaomi 2S mobile phone selected in step S102, according to the type and / or model of the Xiaomi 2S mobile phone, access the pre-configured fingerprint identification algorithm configuration table shown below to obtain the fingerprint corresponding to the Xiaomi 2S mobile phone. Acquisition algorithm A001.

Fingerprint recognition algorithm configuration table

In step S104, a specific collection algorithm is used to collect the feature code to be verified from the human biometric file of the requesting verifier.

After the collection algorithm is selected, the algorithm can be called to collect the signatures to be verified. In this embodiment, the fingerprint authentication center software is written in the Java language, and the C language provided by the Xiaomi 2S mobile phone manufacturer is written in the C language. The function call interface of fingerprint acquisition algorithm A001 is provided in the dynamic link library, so the JNI method is used, taking the fingerprint image file to be verified as an input, and calling the function interface of fingerprint acquisition algorithm A001 provided by the dynamic link library. You can get the signature to be verified.

In step S105, a reference feature code is collected from the reference file, and a collection algorithm used to collect the reference feature code is consistent with a specific collection algorithm used to collect a feature code to be verified.

After obtaining the signature to be verified, further obtain the reference signature.

First, read the reference file of the requesting verifier. In this embodiment, in step S100, the fingerprint image file (ie, the reference file) registered by Mr. Zhang has been stored in the fingerprint database, and the fingerprint is accessed according to the user ID 0001 provided by Mr. Zhang when he submitted the authentication request. Database to find the data record corresponding to the user ID 0001, for example, for the fingerprint database of this embodiment, a similar SQL statement such as "select * from fp_db where user_id = 0001" can be used, in other embodiments For different data file formats and storage locations, other search methods can also be used, which is not limited in the present invention. After finding the corresponding data record, extract the registered device type and / or model from it: Xiaomi 2S mobile phone, extract the storage path and file name of the registered fingerprint image file, access the path, and read the registered fingerprint Image file 0001.jpg.

In other embodiments, for example: using voiceprint for user authentication, the above steps are similar, that is, according to the user ID provided by the user when making an authentication request, accessing the registered data, Describe the data record corresponding to the user ID, and extract the registered data from it Device type and / or model, and the storage path and file name of the registered sound effect file, access the path, and read the registered sound effect file.

Then, the reference feature code of the reference file is collected, and the collection algorithm used is the same as the collection algorithm used to collect the feature code to be verified in step S104, that is, the collection algorithm retrieved in step S103 is also used. The reason why the same acquisition algorithm is used is mainly to meet the requirements of interconnection and interoperability of terminal equipment from different manufacturers. In this embodiment, the fingerprint acquisition algorithm A001 of the Xiaomi 2S mobile phone with the same feature code to be verified in step S104 is selected, and the registered fingerprint image file (that is, the reference file) is used as the input to call Xiaomi using the JNI method. The function interface of the fingerprint collection algorithm A001 in the dynamic link library provided by the 2S mobile phone manufacturer can obtain the registered fingerprint image feature code, that is, the reference feature code.

In step S106, it is determined whether the reference feature code and the feature code to be verified correspond to the same human biological characteristics; if yes, an identity verification request is passed.

After completing the above steps S104 and S105, the reference signature code and the to-be-verified signature code of the requesting verifier have been obtained, and the two characteristic codes are compared to determine whether the requesting verifier has passed the identity verification.

The human biometric code is not a simple numerical value or string, but a template that records human biometric information. Taking the fingerprint feature code as an example, it records the overall characteristics of the fingerprint (for example: pattern, core point, etc.) And local features (for example, information about the orientation, position, and curvature of a certain number of endpoints and bifurcation points). Therefore, to determine whether the two fingerprint feature codes are the same, it is not simply to determine whether they are equal, but to compare the two templates. Matching is a process of pattern recognition. The criterion of judgment is not equal or unequal, but the degree of similarity. The determination of this degree of similarity is related to the type and number of feature points collected by the collection algorithm. The more feature points collected, the smaller the probability of misjudgment. Therefore, for feature codes collected by a collection algorithm provided by a terminal manufacturer, the comparison algorithm corresponding to the collection algorithm provided by the terminal manufacturer should also be used for comparison, so as to accurately identify the feature points in the template Type and number, as well as other characteristics, to improve the accuracy of the comparison.

Based on the above reasons, the method for identity verification using human biometrics provided by the present invention uses the acquisition algorithms used in steps S104 and S105 when determining whether the reference feature code and the feature code to be verified correspond to the same human biometrics. Corresponding comparison algorithm.

In this embodiment, step S104 and step S105 use the acquisition algorithm A001 provided by the Xiaomi 2S mobile phone manufacturer, look up the pre-configured fingerprint identification algorithm configuration table, and retrieve the correspondence with the Xiaomi 2S mobile phone manufacturer's acquisition algorithm A001. Comparison algorithm B001. Similarly, using the JNI method, taking the registered fingerprint image file's feature code (that is, the benchmark feature code) and the feature code to be verified as inputs, the fingerprint comparison algorithm in the dynamic link library provided by Xiaomi 2S mobile phone manufacturer is called. The function interface of B001 performs fingerprint feature code comparison. This function determines that the fingerprint to be verified corresponds to the fingerprint of the same user based on the similarity between the two fingerprint feature codes entered. The result of this comparison will be sent back to the Iphone4S mobile phone used by Mr. Zhang, so that Zhang Xiangengong can pass this remote identity verification and can continue the subsequent remote applications.

In the above embodiment 1, Mr. Zhang uses Xiaomi 2S mobile phone to register fingerprint information, and uses Iphone4S mobile phone to perform remote identity verification. If the existing technology is used, the fingerprint authentication center directly compares the fingerprint feature codes uploaded by the two terminal devices. It was concluded that the fingerprints of the same user were not the same, which resulted in Mr. Zhang's identity verification failure. Using the method for identity verification using human biological characteristics provided by the present invention, the same fingerprinting algorithm is used for the fingerprint image file registered by Mr. Zhang and the fingerprint image file to be verified uploaded by Iphone4S (collection algorithm of Xiaomi 2S mobile phone) Collect the feature code and use the corresponding comparison algorithm (the comparison algorithm of Xiaomi 2S mobile phone) to compare, so that Zhang Xianshenggong passed the remote identity verification and realized the interconnection of different terminal equipment manufacturers.

As shown in FIG. 2, FIG. 2 is a flowchart of a second embodiment of a method for verifying identity using human biometrics provided by the present invention. In this embodiment, the terminal device requesting the verifier provides the human body requesting the verifier. The biometric signature to be verified. The steps in this embodiment that are the same as those in the first embodiment are not repeated here, and the differences will be mainly described below. The following is described with reference to FIG. 2.

Step S200: Receive a human biometric profile corresponding to a specific identity as a reference profile.

In this embodiment, Mr. Zhang uses the Xiaomi 2S mobile phone to register fingerprint information. The fingerprint authentication center receives Mr. Zhang's user ID 0001 uploaded by the Xiaomi 2S mobile phone, the fingerprint image file 0001.jpg to be registered, and the type of the Xiaomi 2S mobile phone. And / or model, and store this information in the fingerprint database to complete the fingerprint registration process of Mr. Zhang.

Step S201: Receive a to-be-verified feature code of a human biological feature collected by the requesting verifier by requesting the verifier terminal device.

The requesting verifier uses the terminal device of the requesting verifier that can provide the biometric signature to be verified, enters the human biological characteristics of the requesting verifier, and requests the terminal device of the verifier to perform the necessary preprocessing on the human biological characteristics input by the requesting verifier. , Using the built-in acquisition algorithm (that is, the acquisition algorithm corresponding to the terminal device of the requesting verifier) to collect the to-be-verified feature code of the human biometrics of the requesting verifier, and initiate an identity verification request for the device for identity verification Or the system receives the signature to be verified of the requesting verifier.

The identity verification request initiated by the requesting verifier terminal device includes, in addition to the feature code to be verified, the user identification of the requesting verifier, the type and / or model of the requesting verifier terminal device, and the user identification of the requesting verifier It is used to extract the registered human biometric file (ie, reference file) corresponding to the user identity from the stored human biometric data, and the type and / or model of the terminal device requesting the verifier is used to obtain the The acquisition algorithm and comparison algorithm corresponding to this device.

In this embodiment, Mr. Zhang needs to perform remote authentication when using the application on the Iphone4S mobile phone. Mr. Zhang entered his fingerprint image through the fingerprint sensor of the Iphone4S. The Iphone4S mobile phone uses the built-in A002 fingerprint collection algorithm. Method, collect the to-be-verified feature code of the fingerprint image to be verified entered by Mr. Zhang, and send an identity verification request to the fingerprint authentication center, the request includes: the to-be-verified feature code, Mr. Zhang ’s user ID 0001, and the Iphone4S mobile phone ’s Type and / or model, fingerprint authentication The center receives the above request information.

Step S202: Obtain the type and / or model of the terminal device of the requesting verifier.

In order to meet the requirements of interoperability of terminal equipment from different manufacturers, the acquisition algorithm used to collect the reference signature must be the same as the acquisition algorithm used to collect the signature to be verified. Because the fingerprint authentication center received the feature to be verified in step S201 Therefore, the acquisition algorithm used by the requesting verifier terminal device to collect the feature code to be verified must be used. To meet this requirement, the type and / or model of the terminal device requesting the verifier must first be obtained.

In step S201 of this embodiment, the authentication request initiated by the terminal device includes not only the feature code to be verified, but also the type and / or model of the terminal device requesting the verifier. Therefore, the corresponding request is read from the authentication request. To obtain the type and / or model of the Iphone4S mobile phone of the terminal device requesting the verification party.

In step S203, according to the type and / or model of the terminal device of the requesting verifier, a collection algorithm used by the terminal device to collect the feature code to be verified is retrieved.

In this embodiment, according to the type and / or model of the Iphone4S mobile phone, a preset fingerprint identification algorithm configuration table is accessed to obtain a fingerprint collection algorithm A002 corresponding to the Iphone4S mobile phone.

Fingerprint recognition algorithm configuration table

In step S204, a reference feature code is collected from the reference file, and a collection algorithm used to collect the reference feature code is consistent with a collection algorithm used by the requesting terminal device to collect the feature code to be verified.

After obtaining the special code to be verified, further obtain the reference feature code.

First, read the reference file of the requesting verifier. In this embodiment, in step S200, the fingerprint image file (ie, the reference file) registered by Mr. Zhang has been stored in the fingerprint database, and the fingerprint is accessed according to the user ID 0001 provided by Mr. Zhang when he submitted the authentication request. The database searches for a data record corresponding to the user ID 0001. After finding the corresponding data record, extract the storage path and file name of the registered fingerprint image file from it, access the path, and read the registered fingerprint image file 0001.jpg.

Then, the reference feature code of the reference file is collected. The acquisition algorithm used is the acquisition algorithm called in step S203, that is, the same acquisition algorithm used to acquire the feature code to be verified. The reason why the same acquisition algorithm is used is mainly to meet the requirements of interconnection and interoperability of terminal equipment from different manufacturers. In this embodiment, the fingerprint acquisition algorithm A002 of the Iphone4S mobile phone is called in step S203. The JNI method is used, and the registered fingerprint image file (that is, the reference file) is used as an input to call the Iphone4S mobile phone. The function interface of the fingerprint acquisition algorithm A002 in the dynamic link library provided by the manufacturer can obtain the registered fingerprint image feature code, that is, the reference feature code.

In step S205, it is determined whether the reference feature code and the feature code to be verified correspond to the same human biological characteristics; if yes, an identity verification request is passed.

After completing the above steps S201 and S204, the reference signature code and the to-be-verified signature code of the requesting verifier have been obtained, and the comparison algorithm corresponding to the acquisition algorithm used in step S201 and step S204 is performed on the two signature codes. By comparison, you can determine whether the requesting verifier has passed the identity verification. The reason why the comparison algorithm corresponding to the acquisition algorithm is selected is because the comparison process is a complex matching process. The specific reason has been described in detail in Embodiment 1, and is not repeated here. Please refer to Embodiment 1. .

In this embodiment, the acquisition algorithm A002 provided by the Iphone4S mobile phone manufacturer is used in steps S201 and S204. The pre-configured fingerprint identification algorithm configuration table is found, and the ratio corresponding to the acquisition algorithm A002 of the Iphone4S mobile phone manufacturer can be called. Contrast algorithm B002. Similarly, using the JNI method, taking the registered fingerprint image file's feature code (that is, the benchmark feature code) and the feature to be verified as inputs, the fingerprint comparison algorithm B002 in the dynamic link library provided by the Iphone4S mobile phone manufacturer is called. The function interface performs fingerprint feature code comparison. The function judges that the feature code to be verified corresponds to the same user as the reference feature code based on the similarity of the two fingerprint feature codes entered. The result of this comparison will be sent back to the Iphone4S mobile phone used by Mr. Zhang, so that Zhang Xian will generate power through this time Remote authentication can continue subsequent remote applications.

In the above embodiment 2, Mr. Zhang used Xiaomi 2S mobile phone to register fingerprint information, and used Iphone4S mobile phone to upload the feature code to be verified. If the existing technology is used, the fingerprint authentication center directly compares the feature code uploaded by the two terminal devices, and will get It was concluded that not the same user, which caused Mr. Zhang's authentication to fail. By adopting the method of using human biological characteristics for identity verification provided by the present invention, the collection algorithm of the fingerprint image file registered by Mr. Zhang is collected by the collection algorithm of the Iphone4S mobile phone providing the feature code to be verified, and then the collection with the Iphone4S mobile phone The comparison algorithm corresponding to the algorithm compares the feature code of the registered fingerprint image file (that is, the benchmark feature code) with the feature code to be verified uploaded by the Iphone4S mobile phone. Because the same collection algorithm is used (the collection of the Iphone4S mobile phone) Algorithm), and the corresponding comparison algorithm (comparison algorithm for Iphone4S mobile phones), so Zhang Xian generated power through this identity verification, to achieve the interconnection of different terminal equipment manufacturers.

As shown in FIG. 3, FIG. 3 is a flowchart of a third embodiment of a method for performing identity verification using human biological characteristics provided by the present invention. In this embodiment, the requesting verifier terminal device may be the one requesting the verifier. The human biometric file may also be a feature code to be verified of the human biometric of the requesting verifier. The steps in this embodiment that are the same as those in Embodiment 1 and / or Embodiment 2 will not be repeated, and the differences will be described below with emphasis. The following description is made with reference to FIG. 3.

Step S300: Receive a human biometric profile corresponding to a specific identity as a reference profile.

In this embodiment, Mr. Zhang uses the Xiaomi 2S mobile phone to register fingerprint information. The fingerprint authentication center receives Mr. Zhang's user ID 0001 uploaded by the Xiaomi 2S mobile phone, the fingerprint image file 0001.jpg to be registered, and the type of the Xiaomi 2S mobile phone. And / or model, and store this information in the fingerprint database to complete the fingerprint registration process of Mr. Zhang.

Step S301: Receive an authentication request corresponding to a specific identity.

The requesting verifier uses a requesting verifier terminal device that can provide a human biometric file or a human biometric to-be-verified feature code, enters the human biological feature to be verified, and requests the verifier terminal device to perform necessary human biological characteristics input by the user. After preprocessing, the human biometric profile of the requesting verifier is generated. The terminal device with the feature code collection function can also use its own collection algorithm to collect the signature to be verified from the generated biometric profile of the requesting verifier, and Initiate an authentication request. The device or system for performing identity verification receives a human biometric file or a signature to be verified of the requesting verifier.

The identity verification request initiated by the requesting verifier's terminal device includes, in addition to the human biometric file or signature to be verified, the requesting verifier's user identification and the type and / or model of the requesting verifier's terminal device .

In this embodiment, when Mr. Zhang uses the application on the Iphone4S mobile phone, remote authentication is required. Mr. Zhang entered his fingerprint information through the fingerprint sensor of the Iphone4S. The Iphone4S mobile phone has the function of collecting fingerprint feature codes, so Iphone4S mobile phone can use its own A002 fingerprint acquisition algorithm after generating the fingerprint image to be verified Method, collecting the feature code to be verified from the fingerprint image to be verified. After that, the Iphone4S mobile phone sends an identity verification request to the fingerprint authentication center. The request includes: Mr. Zhang ’s fingerprint image file to be verified or the feature code to be verified, Mr. Zhang ’s user ID 0001, and the type and / or model of the Iphone4S mobile phone. Fingerprint authentication The center receives the above request information.

In step S302, it is determined whether the received biometric authentication request provides a biometric profile of the human body requesting the verifier, or a feature code to be verified of the human biometrics collected by the requesting verifier by requesting the verifier terminal device; if the request is provided for verification The human biometric file of the party performs step S303; if the provided is a to-be-verified feature code of the human biometric collected by the requesting verifier's terminal device, step S304 is performed.

Because the identity verification request uploaded by the terminal device may provide the human biometric profile of the requesting verifier, or the to-be-verified signature code of the requesting verifier, the device or system used for identity verification receives the identity verification request. After that, the information contained in the authentication request is first read, the type of information to be verified provided by the terminal device is determined, and different steps are performed according to different types of information to be verified.

In this embodiment, if Iphone4S uploads the fingerprint image file of the requesting verifier, step S303 is performed; if Iphone4S uploads the feature code to be verified of the requesting verifier, step S304 is performed.

In step S303, a specific collection algorithm is used to collect the feature code to be verified from the received human biometric profile of the requesting verifier, and then go to step S306 for execution.

Because the terminal device provides the human biometrics of the requesting verifier File instead of the signature to be verified by the requesting verifier, so a specific collection algorithm is used to collect the signature to be verified from the human biometric file of the requesting verifier. In order to achieve the interconnection and interconnection of terminal equipment of different manufacturers, the specific collection algorithm is also used in subsequent steps to collect a reference feature code from a reference file. As a better solution, the acquisition algorithm corresponding to the terminal device of the requesting verifier may be adopted, or the acquisition algorithm corresponding to the terminal device providing the reference file may be adopted.

First, obtain the type and / or model of the requesting verifier terminal device used to provide the biometric profile of the requesting verifier, or obtain the type and / or model of the specific terminal device used to provide the reference file. Then, the acquisition algorithm used by the terminal device is called according to the type and / or model of the terminal device. Finally, the retrieved collection algorithm is used to collect the signature to be verified from the human biometric profile of the requesting verifier. After obtaining the feature code to be verified, go to step S306 for execution.

In this embodiment, one device can be selected arbitrarily from the Xiaomi 2S mobile phone that provides Mr. Zhang's registered fingerprint image file (ie, the reference file) and the Iphone4S mobile phone that provides Mr. Zhang's fingerprint image file to be verified. Xiaomi 2S phone. Then, according to the type and / or model of the selected Xiaomi 2S mobile phone, access the pre-configured fingerprint identification algorithm configuration information, and call the fingerprint collection algorithm A001 corresponding to the Xiaomi 2S mobile phone. Finally, using the JNI method, taking the fingerprint image file of the requesting verifier as input, and calling the function interface of the fingerprint collection algorithm A001 in the dynamic link library provided by Xiaomi 2S mobile phone manufacturer, we can obtain the feature code to be verified of the requesting verifier. . Then go to step S306 for execution.

Step S304: Obtain the type and / or model of the terminal device of the requesting verifier.

Because the terminal device provides the feature code to be verified by the requesting verifier, it only needs to collect the reference feature code for the reference file. In order to achieve the interconnection of terminal equipment from different manufacturers, the acquisition algorithm used to collect the reference signature must be the same as the acquisition algorithm used to collect the signature to be verified. Therefore, before collecting the reference signature, you must first obtain the Type and / or model before selecting the corresponding acquisition algorithm.

In step S301 of this embodiment, the identity verification request initiated by the requesting verifier terminal device includes not only the feature code to be verified, but also the type and / or model of the device that provides the feature code to be verified. The corresponding information is read in the verification request, so as to obtain the type and / or model of the Iphone4S mobile phone of the terminal device requesting the verification party.

In step S305, according to the type and / or model of the terminal device of the requesting verifier, a collection algorithm used by the terminal device of the requesting verifier to collect the feature code to be verified is acquired.

In this embodiment, the pre-configured fingerprint identification algorithm configuration table is accessed according to the type and / or model of the Iphone4S mobile phone of the requesting verifier terminal device, and the fingerprint acquisition algorithm A002 corresponding to the Iphone4S mobile phone is called.

In step S306, a reference feature code is collected from the reference file, and a collection algorithm used to collect the reference feature code is consistent with a collection algorithm used to obtain a feature code to be verified by a requesting verifier.

First, read the reference file of the requesting verifier. In this embodiment, in step S300, the fingerprint image file (ie, the reference file) registered by Mr. Zhang has been stored in the fingerprint database, and the fingerprint is accessed according to the user ID 0001 provided by Mr. Zhang when he submitted the identity verification request. Database to find the data record corresponding to the user ID 0001, after finding the corresponding data record, extract the storage path and file name of the registered fingerprint image file from it, access the path, and read the registered Fingerprint image file 0001.jpg.

Then, the reference feature code of the reference file is collected. In order to meet the requirements of interconnection between different manufacturers' terminal equipment, the acquisition algorithm used to collect the reference signature should be the same as the acquisition algorithm used to collect the signature to be verified by the requesting verifier. If the identity verification request provided the human biometric profile of the requesting verifier, the specific acquisition algorithm selected in step S303 should be used. If the identity verification request provides the signature verification code of the requesting verifier, then The acquisition algorithm retrieved in step S305 should be used.

In this embodiment, if the fingerprint verification file provided by Mr. Zhang is to be provided in the identity verification request, the specific collection algorithm selected in step S303 is adopted, that is, the collection algorithm A001 corresponding to the Xiaomi 2S mobile phone. The verification request provides the feature code to be verified of Mr. Zhang's fingerprint image, and then the acquisition algorithm A002 corresponding to the Iphone4S mobile phone retrieved in step S305 is used. Then, using the JNI method, taking the registered fingerprint image file (that is, the reference file) as an input, and calling the fingerprint acquisition algorithm function interface in the dynamic link library provided by the terminal device manufacturer, In order to obtain the feature code of the registered fingerprint image, that is: the reference feature code.

In step S307, it is determined whether the reference feature code and the feature code to be verified correspond to the same human biological characteristics; if so, an identity verification request is passed.

After completing the above steps, the reference feature code and the feature code to be verified have been obtained, and a comparison algorithm corresponding to the collection algorithm for collecting the reference feature code and the feature code to be verified is used to compare the two feature codes. You can determine whether the party to be verified has passed the identity verification. The reason why the comparison algorithm corresponding to the acquisition algorithm is selected is because the comparison process is a complex matching process. The specific reason has been described in detail in Embodiment 1, and is not repeated here. Please refer to Embodiment 1. .

If the biometric profile of the requesting verifier is provided in the identity verification request, the comparison algorithm corresponding to the specific acquisition algorithm selected in step S303 above is selected; if the identity verification request is provided, the request is provided The feature code to be verified by the verifier selects a comparison algorithm corresponding to the acquisition algorithm retrieved in step S305. Then, the selected comparison algorithm is used to compare the obtained signature to be verified with the reference signature.

In this embodiment, if the iPhone4S mobile phone uploads the fingerprint image file of Mr. Zhang in the authentication request, the collection algorithm A001 of Xiaomi 2S mobile phone has been selected as the specific collection algorithm in step S303 to find the pre-configured fingerprint Identify the algorithm configuration table, and retrieve the comparison algorithm B001 corresponding to the acquisition algorithm A001 of the Xiaomi 2S mobile phone manufacturer. Similarly, if the authentication request is on the Iphone4S phone Passed the signature code of Mr. Zhang's fingerprint to be verified. In step S305, the acquisition algorithm A002 of the Iphone4S mobile phone has been called. In this step, the pre-configured fingerprint identification algorithm configuration table is found, and the acquisition with the Iphone4S mobile phone manufacturer is collected. The comparison algorithm B002 corresponding to the algorithm A002.

After the comparison algorithm is selected, the JNI method is still adopted, and the registered fingerprint image file's feature code (that is, the reference feature code) and the feature code to be verified are used as inputs, and the selected dynamic link library provided by the manufacturer is called. The function interface of the comparison algorithm performs fingerprint feature code comparison. The function determines that the fingerprint to be verified corresponds to the fingerprint of the same user based on the similarity between the two fingerprint feature codes input. The result of this comparison will be sent back to the Iphone4S mobile phone used by Mr. Zhang, so that Zhang Xiangengong can pass this remote identity verification and can continue the subsequent remote applications.

In the above embodiment 3, Mr. Zhang uses Xiaomi 2S mobile phone to register fingerprint information, and uses Iphone4S mobile phone to upload fingerprint image file or feature code to be verified. If the existing technology is used, the fingerprint authentication center directly compares the two terminal devices. The uploaded feature code will conclude that it is not the same user, causing Mr. Zhang's identity verification to fail. With the method for identity verification using human biological characteristics provided by the present invention, the fingerprint authentication center first determines the type of information to be verified provided by the terminal device requesting the verifier, and then performs corresponding operations according to the two types of information to be verified , Using the same acquisition algorithm, collect the registered fingerprint image file's feature code (that is, the reference feature code) and the fingerprint image file to be verified feature code to be verified, and use the comparison algorithm corresponding to the acquisition algorithm , Compare the two above-mentioned feature codes, so that Zhang Xian generates work through the remote body Verification, the interconnection of different terminal equipment manufacturers.
